My RUUD AC condenser fan is no longer turning. Which I believe is preventing the house from being cooled. The motor appears to be working though. Need ac service and repair.

Air Conditioning - Air Conditioning Questions
1.50Where are the air conditioners in high rise apartment buildings and skyscrapers in the USA?
Q.I'm living in Shenzhen, People's Republic of China. I live on the 9th floor of our 34 floor apartment building, and just had to have our external air conditioning serviced. I was alarmed and amazed as our air conditioning technician tied a rope around himself, and then went out the window to the external air conditioning unit to give it a dose of freon (as I held the rope!). My gf asked, what do they do in the USA?
A.In the USA buildings have central Air-Conditioning and the equipment is usually located on the roof of the building.

1.20Outside central air conditioning unit on, blowing air, sometimes a lot, sometimes not, sometimes hot?
Q.I have an outside central air conditioning unit, it is approx. 80 degrees outside and extremely humid, also very hot inside the house with fans running. The air is set to 70*, yet the air coming out of the vents feels to be room temperature and is NOT cooling the house down. Approx. two months ago, the landlord had a technician come out, and he said we had a slow freon leak, and although he filled it with freon, I was told he did not fix the leak. What is causing the air conditioner to do this? I cannot go in 100* weather without air conditioning. Any help would be appreciated :) and thanks in advance!
A.It almost sounds like the tech overcharged the unit. Either way he is supposed to fix the leak. He was not supposed to add refrigerant to a system known to be leaking.
Make sure the fan is working on the outside unit. If it is not the system has no way to remove the heat from your house.
Ask your landlord to call a different tech out to look at it. This guy was a fool.

1.20What is the reason for a slow or stopped central air conditioning outside cooling fan with a loss of cold air?
Q.The recent problem seems to be related to the outdoor cooling fan. The air conditioning system seems to be working properly, but there is a loss of cooling of the air coming from the indoor air conditioning vents. I inspected the outside unit, and yesterday the cooling fan was stopped with a humming/grinding sound. The capacitor looked good (no bulging), but I'm not an electrician and I have no way (or the knowledge) to test voltages and amperages and such. Anyway, I blew on some dust/dirt/cobwebs around some of the wires, and started the system back on and the fan moved at normal speed and the system worked and cooler air came out.
However, today, the indoor temperature wasn't maintained and I went outside and the cooling fan was running much slower (but it was running). After I turned off the system, I felt the metal cover of the outside unit, and it was very hot, and it seemed that the source of the heat came from directly above the cooling fan motor.
Please contact me!
A.Replace your outdoor fan and while your at it replace the capacitor and everything will be fine. But turn your unit off untill you get it fixed or you'll be changing a compressor or buying a new unit.

1.20Annoying humming noise after ducts were cleaned out?
Q.I just got the ducts in my house cleaned out to get rid of pet dander and help me breathe better. The air conditioning is running great now and seems cleaner to breathe in. The only problem is that there is a loud humming noise coming from the big vent on the wall. It only comes from this big vent, and does not resonate from any of the vents on the ground. The big vent is not the original big vent; my contractor replaced it after the ducts were cleaned because the old big vent was dirty.
My contractor says the noise is a result of the air running so openly now, but I'm having a hard time buying that. I think it is the replacement vent vibrating when the air pushes through it. Any thoughts? I'm pretty sure he threw away the old big vent.
A.Call him back and tell him your not satisfied.Lining the duct with duct insulation should help.I think your right about the vibration.

1.20Who should I call to install an exhaust fan in my bathroom? And electrician or an air conditioning company?
Q.We desperately need an exhaust fan installed in our upstairs bathroom. There is one tiny window, which is not enough to expel all of the moisture (esp. living in FL!)... and no air conditioning vent. The bathroom is located on an exterior wall so I wouldn't think it would be too complicated. I just don't know who I should call to do it.
A.Actually, either one can do this job. When building new houses the electrician sets the fan housing and runs the wires, then the AC man runs the duct work when he roughs in his AC unit. Since there's gonna be a switch involved, I'd call an electrician first.

1.20How do I fix a frozen air conditioning filter? How does this happen?
Q.The filter is completely frozen over with ice we cant even remove it.
A.Shut the AC off and let it defrost. Thats usually caused because the filter clogged from not being changed or cleaned. When the filter clogs, air can't circulate and the coils freeze up.

1.10Window air conditioning unit question?
Q.I live in an upstairs condo. I have a small window air conditioning unit. I was going to install it on a shelf outside the window, but my guys said it is fine sitting on the window ledge backed up to the screen of the window and lowering the window down on top of it, as it has exhaust and intake. Any air conditioning experts out there who could tell me if this is a less efficient way for it to run, or is it all right?
A.Unless things have changed, the screen is approx. 3 to 4 inches from window sash ( the glass) the unit is about 14-16 inches deep. they r designed to sit flush to the sash with the upper arm( brace) touching the bottom of the sash u raised to put the unit in.and the slides on the side of the unit slide over to cover the gaps.
i think u would be wise to read the instructions and follow them.
